spectrum of Mylar target, and the 26Al states, which were
observed in the 26Mg(3He,t)26Al spectrum taken under the
same condition as for the Na2CO3 target, were used as
calibration standard. /;

- The B(GT) values were calculated by using the proportionality
(Eq.32) from their peak intensities after excitation-energy
